我们提出了一种集成公交的拼车策略，在这种策略中，私人按需出行服务运营商可以直接上门接送乘客，承诺将乘客送到中转站或从中转站接送，或者在两个不同站点用不同车辆上下车。我们研究了在线求解算法对该策略的有效性。针对该问题定制了排队论车辆调度算法和闲置车辆转移算法。首先用一个合成实例进行了几个实验，以设计和测试这种集成求解方法的有效性，不同模型参数的影响，并衡量这种合作的效益。结果表明，在需求较高的情况下，拼车出行时间可以持续减少40%-60%，而乘客出行时间可以减少50%-60%。对长岛通勤者到纽约市(NYC)的案例研究表明，对于每个区域启动的10-30辆出租车范围内的用户，采用拟议的运营策略可以大幅减少用户旅行时间和运营成本，分别高达54%和60%。这一结果表明，在某些情况下，这种服务是高度必要的。
We propose a ridesharing strategy with integrated transit in which a private on-demand mobility service operator may drop off a passenger directly door-to-door, commit to dropping them at a transit station or picking up from a transit station, or to both pickup and drop off at two different stations with different vehicles. We study the effectiveness of online solution algorithms for this proposed strategy. Queueing-theoretic vehicle dispatch and idle vehicle relocation algorithms are customized for the problem. Several experiments are conducted first with a synthetic instance to design and test the effectiveness of this integrated solution method, the influence of different model parameters, and measure the benefit of such cooperation. Results suggest that rideshare vehicle travel time can drop by 40-60% consistently while passenger journey times can be reduced by 50-60% when demand is high. A case study of Long Island commuters to New York City (NYC) suggests having the proposed operating strategy can substantially cut user journey times and operating costs by up to 54% and 60% each for a range of 10-30 taxis initiated per zone. This result shows that there are settings where such service is highly warranted.
